These gaskets are so stuck on a razor blade wont even take them off. It just shaves them. I think they are the originals but not sure. They have a bead of blueish...stuff around the center of the gasket. I'm gonna try the plastic scraper but don't hold much hope.
I got them off. Thanks for the help. I used a small brush to spread the gasket remover and a plastic scraper. Time consuming but effective. Thanks for the advice.
